Why you have HEIC files
iPhones save photos in the HEIC (HEIF) format by default because it is smaller than JPG at the same quality, which saves space on the phone. But when you move those photos to a Windows PC or try to upload them to an online form or store, they often won't open, or you get an "unsupported format" message.
How to use it
- Drag your HEIC photos onto the box above, or use Choose files. You can select many at once.
- The format is set to JPG. Photos rarely need transparency, so JPG is the lightest and most compatible choice.
- Save them one by one, or press Save all as ZIP to get them in one go.
The first time you add a HEIC photo, the page downloads the tool that reads HEIC, which can take a few seconds. The tool runs inside your browser and your photos are not sent anywhere. In browsers that read HEIC natively, such as Safari, this step is skipped.
Shooting in JPG from now on
On your iPhone, go to Settings → Camera → Formats and choose Most Compatible. New photos will be saved as JPG, at a slightly larger file size. iPhones also often convert photos to JPG automatically when you send them by email or messaging apps. More in how to open iPhone HEIC photos.
